The hydraulic hose plays an important role in the construction field, and today I am happy to share with you the hydraulic hose manufacturing process here, how to manufacture hydraulic hose step by step in our hydraulic hose manufacturer.
How is a hydraulic hose manufactured? You got to know the hydraulic hose structure and a hydraulic hose pipe has three parts, including an inner tube, reinforcement, and outer cover.
We can manufacture the hydraulic hose following its structure, to create a hydraulic hose inner tube, and then reinforcement, and finally outer cover.
So now drive into the part of the hydraulic hose fabrication, to get full about making hydraulic hose, step by step.
Here are go!
Prepare Raw Materials (Synthetic Rubber and Stainless Steel Wire)
At the very beginning of the hydraulic hose manufacturing process, we need to prepare all of the raw materials ahead of time, and here is the synthetic rubber material and stainless steel wire.
You guys can click here to know what hydraulic hose is made of. We will prepare enough raw material rubber in our hydraulic hose manufacturer workshop.
Here is a video showing the rubber compounding process to prepare for manufacturing hydraulic hoses.
Synthetic rubber material
You can see the rubber pieces lying here, get ready to manufacture the inner tube of the hydraulic hose. We use the Banbury rubber mixing machine to mix the rubber material, to make the rubber become the raw material for making the hydraulic inner tube.
Stainless steel wire
At the same time, we also need to prepare the stainless steel wire to get ready for manufacturing the reinforcement of the hydraulic hose.
Here is the stainless steel wire as the raw material to manufacture the reinforcement layer for hydraulic hoses. We source the very long stainless steel wire, up to 50k meters in a roll, to prepare the next step.
And then we need to twist some stainless steel wire together to combine a thick stainless steel wire. The reinforcement of the hydraulic hose is designed to add much more strength to the whole hydraulic hose pipe, in order to work well under high pressure.
The more stainless steel wire can make the hydraulic hose much stronger. Regularly, our manufacturer can combine 7-8 stainless steel wires into one, of course, we can twist the stainless steel wire according to your requirement. Then we will roll the combined stainless steel to the stainless steel cylinder tube.
Extrude the Synthetic Rubber to Create Inner Tube
Now is the time to manufacture the inner tube of the hydraulic hose. We use the rubber extruder machine to extrude the rubber material to create the inner tube.
Here is a steel rod in the rubber extruder machine, to squeeze out the empty rubber tube. And the diameter of the steel rod equals the inner diameter (I.D) of the finished hydraulic hose.
We will get the inner tube of the hydraulic hose after extruding process, and the inner tube has a smooth surface, looking shining.
Rubber extrusion is a manufacturing process used to create rubber hydraulic hoses in continuous lengths. It involves forcing a rubber compound through a die of a specific shape under high pressure.
Hydraulic hoses are a common product made through rubber extrusion. They are essential components in various industries, from construction and agriculture to manufacturing and mining.
Manufacture Reinforcement Layer
Now we prepare the stainless steel wire to create the reinforcement layer of the hydraulic hose. Here are 2 different methods to manufacture the stainless steel reinforcement, so here are 2 types of hydraulic hose we can manufacture in this step, braided hydraulic hose and spiral hydraulic hose.
Braided hydraulic hose
We use the hydraulic hose braiding machine to create the braided reinforcement, to get the braided hydraulic hose.
Here is the video showing you how the braided hydraulic hose is manufactured by the hydraulic hose braiding machine.
And then we will get the semi-finished hydraulic hose with braided reinforcement.
The braided hydraulic hose reinforcement looks like the gold hair braids.
Spiral hydraulic hose
The machine used to manufacture the spiral hydraulic hose is different, and this is the 4-wire spiraling machine for braiding hydraulic hose.
And you guys can see the difference between braided vs spiral hydraulic hoses. and how spiral hydraulic hose is manufactured in this short video.
This is the manufacturing process to make the spiral hydraulic hose in the workshop.
Then we get the finished spiral hydraulic hose reinforcement.
You guys can see the comparison of braided hydraulic hose and spiral hydraulic hose.
Extrude Outer Rubber Cover
And then we need to extrude the rubber to create the outer cover to parcel the reinforcement layer, and this is the third layer of the hydraulic hose, also the last layer.
Print Private Label
In this step, we can customize your private label or your hose company logo on the surface of the outer cover of the hydraulic hose. All of the hydraulic hose specifications and your brand name will be printed on the surface of the hydraulic hose layline.
You can read the basic parameter information from the finished hydraulic hose, and we can print anything you want, such as private label, company logo, hydraulic hose specifications and etc. And at the moment, the hydraulic hose is manufactured with a smooth surface, without any texture.
Create Surface Texture
Next, we can create the texture to make the hydraulic hose cover surface look special, and we use the press cloth to create your desired texture on the hydraulic hose surface, by adding much pressure to the hydraulic hose surface. The rubber material is soft, so the press cloth will leave the designed texture on the surface.
Vulcanize Hydraulic Hose
Then we need to vulcanize the hydraulic hose in the vulcanizing boiler equipment, and the press cloth is really important to protect the hydraulic hose during the vulcanizing process. The rich steam heating will mature the rubber material, making rubber molecules become closer, to give the hydraulic hose stable performance.
Of course, vulcanized rubber is much more stable than natural rubber. The vulcanizing process is also necessary for producing hydraulic hose with high quality.
The vulcanization for hydraulic hose production is the process that changes the synthetic and natural rubber into cross-linked polymers. Sulfur is the vulcanization agent for natural rubber (other chemicals are also used if needed). Vulcanizing hydraulic hoses using sulfur with heat and high temperature can make the hydraulic hose’s physical structure much more durable and stable.
Here, we can make a smooth and wrapped hydraulic hose during this vulcanizing process, using different materials for rubber vulcanization.
Smooth hydraulic hose: Wrap the plastic-coated material before the vulcanizing process, and get the smooth surface of the hydraulic hose.
Wrapped hydraulic hose: Use the water press to wrap the hydraulic hose, to get the special cloth marks overlapping the water cloth after the vulcanizing process, and then remove the water press. the cloth mark will be imprinted on the surface of the hydraulic hose permanently.
If you want to know the differences between the smooth vs wrapped hydraulic hose, please feel free to contact us to get free samples.
And remove the press cloth after the steaming process in the vulcanizing boiler.
We finally get the hydraulic hose printed with specifications after removing the press cloth.
Pressure Test
We need to have pressure testing to test the quality of the hydraulic hose, by measuring the burst pressure and high pressure.
Pack Hydraulic Hose
We will use the hydraulic pipe rolling machine to roll the qualified hydraulic hose after the strict pressure test and get ready for the packing process.
We use the woven bag to pack the hydraulic hose. The packing material is different though, plastic film and the woven bag are the most popular to pack the hydraulic hose, and the packing material is strong enough to store the hydraulic hose inside well. And the packed hydraulic hose rolls are also much easier to be stacked well in the hydraulic hose warehouse before loading time.
What’s more, we can print your logo or something you want on the surface of the hydraulic hose packing material, including your hydraulic hose brand name, hydraulic hose model number and etc. The printed text is helpful for you to know what hydraulic hose is inside the packing film.
Here is a video showing you how to pack the hydraulic hose using the manual hydraulic hose packing machine.
Keep Hydraulic Hose in Warehouse
The finished hydraulic hose will be kept in our big hydraulic hose warehouse before shipping. All hydraulic hose will be stored well, before loading them to the shipping container.
Ship Hydraulic Hose
We will use the forklift with wooden pallets to send the packed hydraulic hose to the container, and the wooden pallets can protect the hydraulic hose away from damage.
Well done!
